OS: xubuntu 16.04.4 LTS
kernel version: 4.13.0-36-generic
When I boot up, I get my BIOS splash screen followed by shiny black screen comes,after that screen blacks out. I have to close laptop Lid to force hibernation and then reopen the lid and then I get the login screen. With this version of kernel I was not able to find any bugs related to hibernation. If I attach a external monitor then I get the login screen directly. I had similar problem with Ubuntu 16.04.4, there was a dark purple light(related to ubuntu) and then the screen blacks out. Had to follow the similar lid process to get the login screen.
